Question

classification of alkanes​

Answer 1

IUPAC defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms".

Answer 2

There are three types of chemical structure of alkanes known such as linear, branched, and cyclic alkanes. Linear alkanes should have the carbons bonded together in a chain-like structure, which is similar to a snake or rope. ... An alkyl group is a group of carbon and hydrogen atoms attached to an alkane molecule.
